CRIUSE CONTROL WAS ENGAGED, WHEN TRIED TO DISENGAGE WILL NOT, WENT INTO OPEN THROTTLE POSITION, TO STOP VEHICLE APPLIED THE BRAKES REAL HARD AND RELEASED. *AK
DURING WARM WEATHER THE VEHICLE'S THROTTLE WILL STICK AT 2000. THROUGH MY RESEARCH I HAVE FOUND THIS TO BE THE FAULT OF THE ECU. IT IS A VERY DANGEROUS THING TO HAVE YOUR THROTTLE STICK. DT

I'VE HAVE EXPERIENCED PROBLEMS OF ERRATIC IDLE SPEED, THE ENGINE REVVING AND DROPPING UNCONTROLABLY AND SPORADIC DYING OF THE ENGINE WHEN I PRESS IN THE CLUTCH. THE PROBLEM HAS BEEN TRACED TO MY DELCO ELECTRONIC CONTROL MODULE BEING FAULTY. THIS FAULTY MODULE UNFORTUATELY CONTROLS ALL OF THE FUNCTIONS OF THE CAR INCLUDING IDLE. THIS IS A HAZARD TO ME AND OTHERS, THE ERRATIC IDLE HAS CAUSES MY (MANUAL) CAR TO LURCH FORWARD UNCONTROLABLY, DURING TAKE-OFF. THE SPORADIC DYING CAUSES THE MOST DANGER. WHEN THE CLUTCH IS PRESSED IN, IN PREPERATION TO STOP THE CAR DIES AND WITH IT BRAKING POWER AND STEERING. THIS LEAVES THE DRIVER ATTEMPTING TO STOP BEFORE BRAKE PRESSURE IS LOST, AND AT THE SAME TIME ATTEMPTING TO RESTART THE CAR IN A VAIN EFFORT... THIS HAS HAPPENED TO ME MANY TIMES, FORTUNATELY I HAVEN'T HAD AN ACCIDENT YET. I AM OUTRAGED THAT ISUZU/GEO CAN ALLOW A CARS TO BE BUILT LIKE THIS, WITH FAULTY COMPUTERS. ITS A SAFETY HAZARD, WHICH THEY EXPECT THE OWNER TO FIX AT AN OUTRAGOUS COST. ITS EITHER FIX IT AND WAIT FOR IT TO HAPPEN AGAIN WITH THE NEW COMPUTER AT A COST TO ME, OR LIVE WITH THE FACT THAT THEY BUILT AN UNSAFE CAR. THIS I FIND UNACCEPTABLE, THATS WHY I'M WRITING YOU, SOMEONE NEEDS TO MAKE THEM FESS UP TO THIER MISTAKE AND FIX IT. *AK
THE IDLE IS VERY ERRATIC. NOT TOO SURE IF IT'S THE CARBURATOR OR NOT, BUT THE IDLE WILL JUMP FROM 950-1000 RPM UP TO 2000. THIS IS VERYODD AND HAVE HEARD OTHERS COMPLAIN ABOUT THE SAME PROBLEM. THANK YOU. *AK
SPORADIC IDLE AND HIGH IDLE FORCES DRIVER TO KEEP FOOT FIRMLY ON BRAKE TO KEEP CAR FROM LURCHING AND GOING TO FAST. COMPUTER RELATED PROBLEM. COULD CAUSE INJURY OR DEATH TO A PEDISTRIAN. NEEDS TO BE CORRECTED. *AK
IDLE BECOMES ROUGH, BOUNCES AND DIES, FAILS TO START OR STARTS AND CHECK ENGINE LIGHT IS ON, RUNS VERY BAD. ONCE CAR SITS FOR A WHILE, STARTS TO RUN FINE, DOES IT WHEN IT IS WARM OUT. *AK
